Abstract

PURPOSE:To make it possible to maintain the aimed car speed with high accuracy without using any complicated mechanism by moving governor pattern in accordance with the difference between the aimed car speed and the present car speed and making feedback control of the fuel injection quantity. CONSTITUTION:The micro-computer 114 is made to issue interrupt signal by the pulse signal of the RPM detecting sensor 100, and the RPM is calculated by this time between pulses, and cyclically accumulates the latest data on the memory, and the car speed SPD is calculated from the time between pulses with the signal from car speed detecting sensor 101. Average RPM Ne for the one revolution of engine is obtained from the accumulated RPM, and the accelerator movement ACC is obtained from the sensor signal of the acceleration position sensor 102, and the basic injection quantity Q is map-searched from those both values, and either smaller one out of this value and the maximum injection quantity QMAX corresponding to the operation condition at that time is decided as final injection quantity QFIN, and the governor pattern of the stored accelerator movement ACC is moved accordingly, and this final result is output to the injection control actuator driving circuit 117.
